Victoria Nuland, Assistant Secretary of State, has said that the sanctions against Russian-occupied Crimea will remain in force until the territory is returned to Ukraine, Ukrinform reports.

"Crimean sanctions will remain as long as the occupation continues,”said Victoria Nuland, speaking at Washington Marshall Fund.

She also commented on current situation as for the Boeing crash in the east of Ukraine, saying that the report on causes of the tragedy would confirm the US position with regards to perpetrators.

“We expect that the Netherlands will unveil the results in a week or ten days. We are sure that the words of John Kerry, the US Secretary of State, said three days after the attack will be confirmed, in terms of persons responsible for the offence and used weapons,” Victoria Nuland said.

She has also stated that it is extremely important to seek out the perpetrators not only for Ukraine but also for the international political system.
